Definition

Noun: - The minimum level or intensity of a stimulus required for a person to perceive it as painful. It is the point at which a sensation transitions from being merely noticeable or uncomfortable to being experienced as actual pain.

Usage

It is often discussed in relation to variability between people. - The doctor explained that the patient's low pain threshold meant they felt discomfort more acutely than others. - Athletes often train to increase their pain threshold to endure intense physical exertion.
